cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects, aggregates, processes, and exports information about running containers. Specifically, for each container it keeps resource isolation parameters, historical resource usage, and histograms of complete historical resource usage. This data is exported by container and machine-wide.

We also have an Automated Build canary release of cAdvisor which is continuously built from HEAD. This can be found in the google/cadvisor-canary image. It is not recommended for production use due to its size and volatility.
